To all whom it may concern:

Be it known that 1, JAMES Srronnoon, a subject of the King of Great Britain, residing at 40 Tockholes Road, Darwen, Lancashire, England, have invented certain new and useful Improvements in Apparatus Suitable for Use in the Drying of Printed Wall Papers, of which the following is a specification.

The invention relates to apparatus known as hanging tackle suitable foruse in the drying of printed wall papers, and has for object to provide means whereby the flexible material to be passed through said apparatus is taken from a feeding device, and may be carried through a drying chamber, said material being afterwards deposited for removal or storage purposes.

WVith reference to the accompanying drawings illustrating one form of the apparatus, and adjacent parts, Fig. 1 is a side view of a portion of Fig. 2; which latter is a plan view of the main portion of apparatus arranged according to my present invention. Fig. 3 is a sectional view through line A. B. of Fig. 2.

()nan enlarged scale, Fig. l is a sectional elevation through line C. D. of Fig. 5, said latter figure being an enlarged view of the right hand portion of Fig. 3.

Fig. 6 is a half sectional view through line E. F. of Fig. 5.

Fig. 7 is a view in elevation showing a small portion of a feeding device of ordinary and well known character employed in a wall paper drying plant, and also showing mechanism, which is external to the part of apparatus in Fig. 3, concerned with the transfer of the flexible material from the feeding mechanism named to the part of the apparatus shown in said Fig. 3.

In said Fig. 7, a member marked .2, is placed in front of a part marked 10 for the sake of extra clearness.

Fig. 8 is a repetition of a portion of the upper part of Fig. 7, with a member therein indicated in a new position by means of broken lines.

Fig. 9 is a plan view of Fig. '7, and shown adjacent to a portion of Fig. 5, said Fig. 9 being in a plane parallel-to that of Fig. 2.

Fig. 10 is a diagram view with reference to-the feeding device referred to, and Fig. 11 is a similar view with reference tothe delivery end of the apparatus. Fig. 12 is a plan View of a portion of Fig. 11.

With reference to Figs. 1 to 6 inclusive, a, is a continuous flexible member or chain, here assumed to be arranged with its broad part in a vertical plane, and b is another and separate chain similarly arranged. These chains are capable of being carried along by chain wheels 0 and d respectively. These wheels are mounted on shafts e and f re spectively, which shafts are mounted in suitable bearings at their extremities, such as bearings at the roof and flooring of the room in which the, apparatus is provided. One or more of such shafts may be driven by any suitable power.

At intervals along the chain a there are provided hinges 9 here consisting of a pair of plates pivoted at it (see Fig. 5 more par ticularly, and Fig. l). That is to say, one of the plates aforesaid is attached to" chain a and the other, and pivoted one, toashoelike part i in connection with a rod j in each case. Thus there are a series of said rods situated atintervals along the chain a. The connection named consists of a boss 70, to which part 70 each rod is pivoted at Z (see more particularly Fig. 4). It will thus be seen that when allowed to do so, each rod may swing on its hinge in a horizontalplane, and on its pivot in a vertical plane.

. The outer parts of the rods j are arranged to rest upon the upper edge of the chain 6 for a considerable portion of the operation to be described. But it will be seen on reference to Fig. 2 that the chain 6 will cease to support the rods as they come to such part of the apparatus or just prior to reaching point P indicated in Fig. 2, on account of the rods aforesaid being carried by chain a beyond the extremity of chain 1). At such time, each rod, in turn, falls to a more or less vertical position (see Fig. 4). When the rods are in a depending position I prefer to provide a guide for the shoes 2', which guide, or one form thereof, is indicated at m in Fig. 5. A casing for the apparatus in Fig. 2 is indicated atnin Figs. 2 and 5, which casing has its top edge well below the level of the rods y for the most part, but at the right hand end of theapparatus, this casing is assumed to rise in level, and be provided with inclines indicated at 0 in the figures last referred to.

That is to say, these'inclines tend to raise the rods j on their pivots Z as said rods come in contact with said inclines under compulsion by means of the moving chain a. The

effect of the inclines ishowever twofold, in the first place the rods are brought thereby into a horizontal position again, and the friction between them and the inclines during the onward motion, tends to open the hinges g in manner indicated in Fig. 5 more particularly. The object of this latter operation is to bring ach rod into a condition suitable for the same to be swept round at a certain time, by the rapid closing of each of said hinges in turn.

.When' the rods 7' are in the depending condition before referred to, any loop or festoon of material thereon may thus be allowed to slide off said rod,- or be deposited on to any ordinary or suitable kind of receiving device. ut the sweeping action already referred to, on the part of the rods j is to enable the same taking up or becoming provided with'a fresh loop or festocnof mate-- rial. This latter action canv better be un derstood by additional reference to Figs. '7 to 9 inclusive.

p are arms pivoted at g in each case, the latter being for example shafts supported from the roof of the room or adjacent room to that, containing the apparatus in Fig. 3. One of these arms is shown provided at r with an end capable of coming in contact with a knife edge or similar device 8 attached to or forming part of a bar 6 which latter bar is the ordinary bar provided in a Well known form of feeding device, said bar being carried round by and upon a. chain a mounted on a chain wheel 1), the latter forming one of aseries in said well known machine or device. In Fig. 7 the bar 2, shown in several positions. In this figure andin Fig, 9 the wall paper or material is shown at'w and resting upon bar t. A. bar

01 connects the two arms p together, and the one on the right in Fig. 9 is shown connected by rod y to a member 2 having provided an abutment end at l. The bar a is pivoted at 2 on the connection y, so as to enable the abutmentend 1 to rise when necessary (see being such that when the bar t or the part 3 thereof strikes the part 1' of an arm p, the shoeof a rod j is in position to be struck as a consequence by the abutment end of the bar or member 2.

The effect of this is to close rapidly the :hinge. whereby the rod is attached to the chain a,- the length of such rod resulting in a rapid sweeping movement at and near its outer end, Such rod is arranged to come below the level of the bar if and to come against the side of the loop of paper or material resting on said bar and the rod j in advance of the one being swept round as stated, and the material is supposed to be hanging down in a loop between the supports namedpthe effect of the motion described is to cause the rod involved to engage and take upon itself the looped material from the bar 6, which bar is carried round by the chain it to be fed with a loop of material forming a continuation ofltliat under consideration, and in manner forming no part of my invention. A spring 3 is shown in Fig. 9 for bringing the arms 70, and consequently the abutment on bar or member a back to the initial position. after each forcing round of arod j as described.

The arrow'lines in the various figures indicate directions of motion of the parts to which they relate. By th'emeans described, when printed wall paper-is required to be carried in festoon form through a drying chamber, the operation is performed by the rods 7' which are capable when necessary of a twofold movement in planes at right angles with each other, one of which movemerits enables the material to be deposited- It is to be observed that, the material or paper to of one continuous length from end to end, hangs between the bar t and the" last rod j supporting the other side of a loop thus formed of said material, ready for a further and consecutive rod'to be swept into position as described, for coming against the part of the material hanging from. the bar t, and so allow the material to fall naturally on to said rod j, as'the bar 16 travels on'and round wheel 4) in its continuous journey through the feeding mechanism of ordinary character, said mechanism being provided with chain it in continuous form.

The operation would be similar if said feeding 'mechanism were provided with more than one bar If at suitable intervals, in which case the relative speeds of travel as between chain it and ranged to suit.

With reference to'the feeding mechanism in relation to the present apparatus, in Fig. 10'the rods j are assumed to be moving inthe direction of the arrow line above them, the last of which rods to be moved round into chain a would-be arposition by the movement of chain a being ferred to, by the rapid closing of its hinge, it will come against the depending part of the paper from bar 25, and eventually remove the paper therefrom in the form of a festoon. The bar 2? is rapidly moved round on chain u so as to engage a further loop of part of the paper which is assumed to be continually moving in the direction indicated by arrow line above it on the right. The operation is thus repeated by another rod j being brought into position as already described.

The process of removal of the dried paper is illustrated in Figs. 11 and 12. The rods 7' therein shown being on the opposite side of the apparatus to the ones in Fig. 10, are also moving in the opposite direction. Removable rods 4, which may be inserted by hand as required, are carried across side chains and wheels 6 and 7 respectively, by being placed in brackets 5 fixed to said chains. The extreme rod 3' on the right in 'Fig. 11 is assumed to be just about to fall into the depending position, or is about to reach the position just prior to position P in Fig. 2. WVhen it does fall, the loop of paper to which was resting on it, falls on to the rod 4 immediately below, and which is being moved upwards by reason of the movement of the chains 6 indicated by arrow line. The loops thus transferred to rollers or rods 4 are carried along as indicated, until they fall out, consecutively, of the supports or brackets 5, on to the inclined bars 8, down mounted on movable continuous chains, pivots for enabling each of said rods to turn in a vertical plane, and hinges for enabling each of said rods to turn also in a horizontal plane, inclined surfaces operating by contact to move each of said rods on its hinge for opening the latter, as well as for raising said rod, together with a movable abutment member operated by movable arms in intermittent contact with a moving part of an ordinary feeding mechanism of a wall paper drying plant, said movable member operating to strike near the root end of each of said rods in turn, for causing the latter to sweep rapidly round in the horizontal plane referred to, or rapidly to close the hinge aforesaid, all in manner and for the purpose substantially as herein set forth.

In testimony whereof I have aflixed my signature.

JAMES SHORROOK.
